AUTOMATIC ATTACHMENT FOR WORKING SHIPS PUMPS.

SPECIFICATION forming part of Letters Patent No. 348,956, dated September 14, 1886.

Application filed January 9, 1886.

Serial No. 188,147. (No model.)

To aZZ' whom it may concern:

Be it known that I, ED\VARD EVERDING, of Eureka, I-Iumboldt county, State of California, have invented an Improvement in Automatic Attachments for Vorking Ships Pumps; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an engine or attachment for operating pumps on vessels, buoys, &c., where the-rolling or pitching motion can be utilized for the purpose.

It consists of a cylinder having a piston working within it, and a pist0n-rod which is connected with the handle of the ordinary ships pump. The cylinder has a pipe extending from its lower end, either directly through the bottom of the vessel or otherwise, so as to enter the water, so that the rising and falling of the vessel in the water operates the piston, and through it the pump. In connection with this are valves and pipes,which will be more fully explained by reference to the accompanying drawing, in which the figure is a side elevation of a vessel, with section showing the apparatus.

A is the ordinary ships pump, having a pipe, 13, extending down into the hold of the vessel, in the usual manner, and the handle 0, by which it is worked. This handle has its end connected by a link or yoke, D, with the piston-rod E, which extends upward from the piston E, working within the cylinder G.

H is a guide through which the piston-rod passes, so as to preserve its axial line as it moves up and down.

I is a pipe extending out from the bottom of the cylinder, which may pass directly through the bottom of the vessel, as shown, or it may lead over the side and extend downward,or in other suitable way be carried down, sothat its lower end is constantly below the'surface of the water. The cylinder being open at the top, it will be manifest that as that portion of the vessel where the pump and cylinder are situated rises and falls by the rolling or pitching of the vessel the water in the pipe I will seek its level with that upon the outside of The action will then be as follows: When that portion of the vessel rises,the water in the pipe will sink, and the atmospheric pressure within the cylinder forces the piston downward. XVhen that portion of the vessel sinks or settles down into the water, the water will rise in the pipe, and thus force the piston, with its red and connected pump-handle, up again, and the movementis thus continued as the vessel rises and falls. If the vessel rolls or pitches so heavily as to draw the piston down to the bottom of the cylinder, the piston will pass below the mouth of the pipe J,which connects with the side of the cylinder, and also with the pipe I below the cylinder, and air will be allowed to pass through the pipe J and the check-valve K, which is fixedin the pipe, thus relieving the pressure on the piston by admitting air from above to the pipe I below. This will allow the water in pipe I to fall as far as it will, and when the vessel again begins to settle the valve K will close, and the water rising in the pipe I will force the piston to the upper end of the cylinder. If it passes above the check-valve L at the upper end of the cylinder, the air below the piston will be allowed to escape through the valve, and thus relieve the pressure upon the piston in its upward stroke.

\Vhen it is desired to stop the attachment, it can be done by simply opening a valve at M, which allows air to pass freely into and out of the pipe I as the water rises and falls in the pipe. It will be manifest that the length of stroke may be regulated by the position of the check-valve L, which may be placed lower down in the cylinder, if it is desired to shorten the stroke. The sizes of the cylinder and the pipe I will depend upon the size of the pump, depth of hold of the vessel, and the power required to operate the pump.

As the attachment is automatiein its oper' ation, it may be employed upon vessels or upon buoys to keep them clear of water, and will need no attention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent. is

1. A cylinder fixed upon a floating vessel or buoy having a piston and piston-rod connected with the operatin'gleverof a pump, in combination with a pipe extending into the water from the lower end ofthe cylinder, so that the piston maybe operated by atmospheric pressure caused by the rise and fall of the water scribed.

2. The cylinder having its upper end open, provided with a piston which reciprocate's within it and is connected with the handle or lever of a pump, as shown, and a pipe extend ing from the bottom of the cylinderdownward below the surface of the water, with a reliefpipe connecting the cylinder with the pipe, and having a valve, K, within it, substantially as herein described.

3. The cylinder, with its piston connected with the pump handle or lever, and the pipe extending downward into the water, in combination with the relief-valves K and L at. the lower and upper ends of the cylinder, respect ively, substantially as herein described.

4. The cylinder having the reciprocating piston connected with the ships pump or lever, and a pipe extending downwardly from the bottom of the cylinder into the water, so that its lower end will be submerged, in combination with the pipe connecting with the waterpipe below the cylinder, and having-the relief-valve for the admission of air into its upper end, substantially as herein described.

In witness whereof I have hereunto set my hand.

EDWARD EVERDING.
